Learn Linux, visually.
Click, drag, and break things to see how the modern web really works.
Linux
The OS your servers actually run.
Git
Version control without the fear.
APIs
The contracts that connect every system on the web.
DNS
How a name becomes an address.
TLS
How a connection becomes private.
Languages
Paradigms, types, memory, concurrency — the mental models behind the syntax.
Libraries
Package managers, semver, dependency graphs, and tree-shaking — how modern libraries actually ship.
Frameworks
Routing, rendering, build pipelines, and edge runtimes — how a framework wires it all up.
Docker
Build images, run containers, ship anywhere. Watch a Dockerfile turn into a running app, line by line.
Kubernetes
Scale, heal, orchestrate. Watch a cluster recover from a crash without paging anyone at 3 AM.
Every topic, taught visually
Pick a topic and learn it through interactive walkthroughs for tech foundations, code, and cloud. No installs, no setup, no terminal — just illustrated playgrounds in your browser.
Why visual learning?
A lot of what makes computing hard is invisible: packets moving across the internet, containers booting, branches diverging in a Git history. Reading about it rarely sticks. We turn that invisible state into something you can click, drag, and break — so the mental model actually lands.
Who is this for?
Engineers, students, SREs, and curious readers who want to understand how systems actually work — not just memorize commands.
